Question

You are given the following chemical equation:

\[\ce{Mg_{(s)} + CuO_{(s)} -> MgO_{(s)} + Cu_{(s)}}\]

This equation represents:

विकल्प

• decomposition reaction as well as displacement reaction.

• combination reaction as well as double displacement reaction.

• redox reaction as well as displacement reaction.

• double displacement reaction as well as redox reaction.

Answer 1

Redox reaction as well as displacement reaction.

Explanation:

This is a displacement reaction because the more reactive metal, magnesium (Mg), displaces the less reactive metal, copper (Cu), from its oxide compound. It is simultaneously a redox reaction because magnesium gains oxygen (undergoes oxidation) while copper oxide loses oxygen (undergoes reduction).
